Specification of Letters Patent.

Patented Mar. 21, rare.

Application filed April 13, 1915. Serial No. 21,028.

To all whom it may concern Be it known that 1, Isaac J. Ln FEVRE, a citizen of the United States, residing at Atlantic City, in the county of Atlantic and State of New Jersey, have invented new and useful Improvements in Pursing-Winches, of which the following is a specification.

This invention relates to winches and more particularly to pursing winches and the principal object of the invention is the provision of simple and efficient means for winding the opposite ends of the pursing line or bridle of purse nets.

N hen a seine or purse net is pursed it is customary for the operator in the purse-boat to draw one of the opposite ends of the bridle or purse lines alternately; in other Words, one end of the line is drawn in for a predetermined distance and allowed to remain idle while the opposite end of the line is drawn in for a predetermined distance. This alternate drawing of opposite ends of the bridle or purse lines produces a better job of pursing than can be accomplished by the simultaneous drawing in of both ends of the line.

It is, therefore, the object of this invention to produce a simple and eiiicient winch driven from any suitable source of power which will automatically draw in or wind opposite ends of the purse line or bridle without the use of clutches, automatic shifting mechanism or a multiplicity of gears.

Another object of the invention is the provision of mechanism of this character which may be operated either to alternately draw opposite ends of the line or to draw both ends simultaneously when found desirable.

Further objects of the invention will appear as the following description is read in connection with the accompanying drawings, which form a part of this application, and in which Figure 1 is a plan view. Fig. 2 is a longitudinal sectional view. Fig. 3 is a detail horizontal sectional view showing in dotted lines the alternative position of the nigger.

heads.

Referring more particularly to the drawing, 1 represents a base of any suitable character upon which is supported the bearing boxes 2 having the driven shaft 3 mounted therein. This driven shaft has keyed thereto a worm wheel 4 which is driven by the Y worm'5 on the driving shaft 6. This shaft may be the driving shaft of a hydrocarbon engine or may be connected in any suitable manner to the driving shaft of a hydrocarbon or other engine or may be operated by a crank, if desired.

Secured to opposite ends of the shaft 3 are cranks 7 having removably connected thereto the Wrist pins 8 upon which are keyed or otherwise secured the nigger heads or drums 9. The wrist pins as here shown are in the form of bolts which are threaded into the outer ends of the cranks 7 or threaded into apertures 10 formed in the ends of the shaft 3 which project through the cranks 7 as shown in Fig. 3. When the nigger heads are arranged eccentrically to the axis of the shaft 3 the ends of the purse line or bridle which are attached thereto will be alternately drawn .in or have alternate increments of movement as the nigger heads rise from the foremost position of the cranks to the rearmost position thereof while during the remainder of the movement of the cranks or from their rearmost position to their foremost position the line will remain practically stationary as the winding of the same upon the nigger head is oflset by the forward motion.

What is claimed is 1. Mechanism for operating pursing lines for purse nets comprising a driven shaft; and drums arranged eccentrically to the axis of the shaft and connected directly thereto for rotation with the shaft.

2. Mechanism for operating purse nets comprising a driven shaft, a pair of drums arranged to be connected to opposite ends of the line, and means for connecting the drums to the shaft eccentrically to or concentrically with the axis thereof.

3. Mechanism for drawing pursing lines of purse nets comprising a driven shaft, cranks fixed to opposite ends of the shaft and arranged in opposite directions, and

drums secured to the cranks and arranged eccentric to the axis of the shaft.

l. Mechanism for drawing pursing lines of purse nets comprising a driven shaft, 0ppositely arranged cranks secured to the ends of the shafts, a drum for each end of the line, and means for removably connecting the drums to the cranks eccentric to the axis of the shaft or to the shaft concentric with the axis thereof.
